Cortical Structural Connectivity Alterations in Primary Insomnia: Insights from MRI-Based Morphometric Correlation Analysis

Figure 1

Vertex-wise cortical thickness analysis. (a) Differences in cortical thickness between patients with primary insomnia (PI) and healthy controls (HC), removing effects of age, gender, and global mean cortical thickness. (b) Correlations between vertex-wise cortical thickness and PSQI score removing effects of age, gender, and global mean cortical thickness. No differences and correlations survived the correction for multiple comparisons. Trends (, uncorrected) are shown here.
